The 47-year-old Space Master projector in the Vadodara Municipal Corporation's planetarium at Kamatibaug has been down for the last one and a half months due to technical reasons. Because of this, visitors to the planetarium cannot experience educational programs. Last year, in January, the projector was also closed, and it took five months to repair the machine. After a trial run, it had been functioning properly for the past eight months, but it has again stopped working during recent shows.
